METHOD AND APPARATUS FOR BEAT- ING XVIC EIE-GLA$S.

Patented Dec. 2, 191e,:

;' Application filed February 28, 1917, Serial No. 151,582. Renewediii'une 11, 1919. Serial Ito.- SOs/4%.

To all fwhom it may concern:

BL. 1l'. known that l, IRVING a citizen of the United States of'America,

Lucas,-State of Ohio, have invented certain and Apparatus for Drawing Wire-Glass, of which the following is a specification, ref- This invention relates to the artof making sheet glass. The object of the invention after described and is to provide a process and apparatus whereby, sheet glass of uniform. width and thickness maybe drawn from the molten mass and a wire mesh or wire cloth may be drawn in the sheet so as to make what-is known as-wire-- glass;- all as more fully hereinspeciiically pointed out in the'elaims; i

In the drawings Figure 1 is a vertical oen tral longiti'idinal section througha machine embodying my invention and Fig. 2 is a partial side elevation of the same,

The invention in general as shown herein may be subst-antiallyof the type shown in my pending application Serial Number 54,714, filed October 8, 1915, in: which the and comprises a drawing table, A, which may be of the type shown in that application or in my Patent No. 1,122,192, issued December 29, 1914, which, as well known, comprises endless chains, one supported in a horizontal plane and the other pressing upon it from above and drawing it from the tank and delivering it to the leer. I also provide a melting tank, B, and a cooling chamber, C, in which the glass may be more or less tempered, and a drawing chamber, D, the back of which may be formed by a tile. E, forming a narrow trough-like body'- of glass from the front edge of which the sheet, F,-is drawn by the drawing table. I

show belowthe tile' E a heatinig chamber,

G, and a valve, H, which-may be raised more or less above the surface of the glass to assist-in controlling the temperature at the drawing point. A pair of rolls, 1, are situated a short distance from the edge of the drawing table, these rolls being driven and being hollow for the purpose of cooling. The surface may be plain or figured, as desired. 4

1V. CoLsURN,

I also show adriven supporting roller,

through which water may be circulated aboveand I said K. is'a gas' 'i e for en 1 in flame if desired, to the di awing n23 i g P- is the heating chamber for discharging. the heat into the drawing chamber.

Q is a roof which may extend over the span between the drawing chamber and the tank. V 1ft is a roller, preferably of vitrified material and preferably driven, although it may be an idler, the lower edge of which dips nto the glass, as'plainly shown in the, drawings. Above this roller is a slot, S, through which passes a wire clothfT, being held from contact with the walls by a roller, T. The wire cloth as shown is supported .on a roller, U, above the tank, and the same being led down through the-slot S and over the rollerR and carried beneath the surface of the glass between the rolls 1, will be drawn into the sheet midway between the surfaces as the sheet is drawn, as clearly indicated in the drawings.

- Having thus described my invention, what I claim as new and desireto secure by tters Patent is: 1. The method of drawing wire glassconsisting in guiding the wire cloth into the below the sheet between the rolls mass ofinolten glass, drawing the molten glass in sheet form, horizontally, parallel with the surface, with the wire cloth embedded therein.

2. In an apparatus for drawing wire glass the combination of a guide'for leading wire cloth into the mass below the surface and means for drawing the sheet of glass along the plane of the surface of the wire horizontally? in line with the bottom of the roll. i.

4. In a wire glass drawing epparatusthe combihation of a drawing chamber having r fire an open end, a pair of drawing rolls adjaa wire fabric into the glass in the tank and feeding it along said passage with the flow of glass.

6. In an apparatus for forming wire glass, the combination of a tank having an over flow outlet passage arranged for the flow of glass in a sheet, means for directing a wire tank and feedfabric into the glass in the ing it along said passage with the flow of glass, and means beyond the outlet to support and draw the sheet of glass in the direction in which it moves through the passage.

7. In an apparatus for forming wire glass, the combination of a melting tank having an outlet arranged for a flow of glass from the surface of the pool'in a continuous sheet, means to direct a wire fabric into the glass in the tank and with the flowing glass through said outlet. i

8'. In sheet glass forming apparatus, the combination of a tank for molten glass having a horizontaloverflow surface just below the normal surfaceof the glass, arranged to permit the glass to move in a continuous sheet thereover, means to direct a wire fabric into the glass in the tank and along said overflow surface beneath the surface of the glass, and means beyond the outlet to support and draw the sheet.

9. In sheet glass forming apparatus, the combination of a tank for molten glass, means to feed a wire fabric downward into the molten glass in the tank, and means to draw a sheet of glass with'the wire fabric embedded therein horizontally from the tank.

10. In sheet glass forming apparatus, the combination of a tank for molten glass, sheet drawing means beyond the tank for v drawing the glass horizontally from the the level of theiglass, permitting the glass to flow in a continuous sheet thereover, sheet drawing means beyond the tank for drawing the glass in a sheet from said outlet, means for embedding a wire fabric in the sheet, comprising a roll dipping into the glass in the tank, and around the under surface of which the fabric is guided and from which it extends to the sheet feeding means.

12. The method of forming wire glass,

which consists in flowing molten glass in a continuous sheet from the surface of a pool of glass, drawing the glass as it passes beyond .the tank, directing a wire fabric into the tank, and causing it to advance with the flow of glass.

13. The method of forming wire glass,

which consists in drawing a sheet'of glass horizontally from. the surface of a pool of molten glass and directing a wire fabric into the pool,'and thence "horizontally with the flow of glass from the pool.

In testimony whereof I afiix my signature in presence of two witnesses.
